Pada asasnya, saya mengikuti siaran saya ini dan jika saya perlu memaparkan butang radio dan div di dalamnya, penyelesaian berikut berfungsi dengan baik:
$(".tier1-options :radio").on("change", function (e) { //remove shown class from all tier2 options and clear values from all form elements inside it $('.tier2-options') .removeClass('shown') .find('input, select').val('') //show the related tier2 options $(this) .parents('.tier1-options') .find('.tier2-options') .addClass('shown') });
.tier2-options { display: none; margin-left: 1rem; padding: 1rem; background-color: #EEE; } .shown{ display: block; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <h5>Select one of the checkboxes:</h5> <div class='tier1-options'> <label> <input name="useroption" type="radio" value="changeLocation"> Change Location </label> <div class="tier2-options"> <select name="availableMarkAsFullLocations"> <option value="-">--Please Select--</option> <option value="3">BOX#3</option> <option value="6">FREEZER#1</option> <option value="8">FREEZER#2</option> <option value="19">BOX#9</option> <option value="20">QBUILDING</option> </select> </div> </div> <div class="tier1-options"> <label> <input name="useroption" type="radio" value="updateLocation"> Update Location </label> <div class="tier2-options"> <select name="availableUpdateLocations"> <option value="-">--Please Select--</option> <option value="3">BOX#3</option> <option value="6">FREEZER#1</option> <option value="8">FREEZER#2</option> <option value="19">BOX#9</option> </select> </div> </div> <div class="tier1-options"> <label> <input name="useroption" type="radio" value="retireLocation"> Retire </label> <div class="tier2-options"> <select name="availableRetireLocations"> <option value="-">--Please Select--</option> <option value="3">BOX#3</option> <option value="6">FREEZER#1</option> <option value="8">FREEZER#2</option> <option value="19">BOX#9</option> <option value="20">QBUILDING</option> </select> </div> </div>
Tetapi apabila saya cuba menambah berbilang butang radio, kod ini tidak berfungsi dengan pilihan Tier I Move
atau Tier II Move
移动内容
选项。基本上,当我点击Tier I Move
或Tier II Move
subtier2-options
, subtier2-options
tidak muncul
$(".tier1-options :radio").on("change", function (e) { //remove shown class from all tier2 options and clear values from all form elements inside it $('.tier2-options') .removeClass('shown') .find('input, select').val('') //show the related tier2 options $(this) .parents('.tier1-options') .find('.tier2-options') .addClass('shown') }); $(".subtier1-options :radio").on("change", function (e) { //remove shown class from all tier2 options and clear values from all form elements inside it $('.subtier2-options') .removeClass('shown') .find('input, select').val('') //show the related tier2 options $(this) .parents('.subtier1-options') .find('.subtier2-options') .addClass('shown') });
.tier2-options { display: none; margin-left: 1rem; padding: 1rem; background-color: #EEE; } .shown{ display: block; } .subtier2-options { display: none; margin-left: 1rem; padding: 1rem; background-color: #EEE; }

Apabila anda menggunakan kelas dalam fail css, kelas akan digunakan mengikut susunan ia ditulis. Kerana
shown
类位于subtier2-options
类之上,因此它首先被应用。因此,当应用subtier2-options
时,显示设置为block
,然后更改为none
.Anda hanya perlu menukar susunan kelas dalam css seperti yang ditunjukkan di bawah dan kemudian ia akan berfungsi.
